Remove module from hash when it's gone

Module was never being removed from hash table. Therefore, if we create
a module, unref it and create it again we will access freed memory.
Commit "53385cf Improve test of double references" introduced a new test
in test-mod-double-ref.c that previously to this commit was crashing and
now it's working fine.
